(Phys.org)—A team of interdisciplinary researchers at Rensselaer Polytechnic Institute has developed a new method for significantly increasing the heat transfer rate across two different materials. Results ...

Microelectromechanical systems (MEMS) are incredibly tiny devices, often built on the scale of millionths of a meter. Conventional MEMS structures tend to be made out of silicon-based materials familiar to the micro-electronics ...

Scientific research has provided us with a fundamental understanding of how light (via photons) and electricity (via electrons) move within and between materials at the micrometer or nanometer levels, making possible a wide ...

(Phys.org)—Researchers from North Carolina State University have developed new techniques for stretching carbon nanotubes (CNT) and using them to create carbon composites that can be used as stronger, lighter ...

Thermoelectric generators can make better use of the excess heat generated by machines by converting temperature differences directly back into electricity. Now, Masaki Takata from the RIKEN SPring-8 Center, ...

(Phys.org)—An important test is coming up next week to see whether a heat shield made from the soil of the moon, Mars or an asteroid will stand up to the searing demands of a plunge through Earth's atmosphere.

Graphene has caused a lot of excitement among scientists since the extremely strong and thin carbon material was discovered in 2004. Just one atom thick, the honeycomb-shaped material has several remarkable ...

The intense interest in harvesting energy from heat sources has led to a renewed push to discover materials that can more efficiently convert heat into electricity. Some researchers are finding those gains ...

(Phys.org) -- Researchers are developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components to potentially recover energy wasted in factories, power plants and cars.

A North Carolina State University researcher has developed a more efficient, less expensive way of cooling electronic devices  particularly devices that generate a lot of heat, such as lasers and power devices.
